Application filed April 14, 1924.

This invention relates to paper tube packages and is particularly adapted tor packaging continuous tubes, such as blasting tubes.

I provide a paper tube package having an open center, a portion of the tube ad acent one end thereof departing from the regular windings and projecting into the open center. With this form of package, access to the inner end of the tube may be easily had, whereby lengths of tubing may be withdrawn from the interior of the package, as required, without disturbing the outer wrapping thereof. This is particularly desirable in a miners blasting tube package, since the package is subjected to considerable handling and usage before it has been entirely consumed, and it is highly advantageous to provide a package Wh1ch will not unwrap or lose its tight wound character at any time.

I further provide for sealing the outer end of the package without resorting to a separate sticker, by utilizing the binding strip which forms apart of the tubing.

In the accompanying drawings illustrating a preferred embodiment of the present invention,

Figure 1 is a side elevation showing the manner in which a tube package is formed according to my invention; and

Figure 2 is a perspective view of a completed package.

In the illustrated embodiment of the in vention, there is shown a blasting tube package formed from a blasting tube made of a paper strip 3 formed into tube form and having an adhesive strip 4 over the same. This sealing strip may be provided with graduations 5, as set forth in the copending application of George S. Clark, Serial No. 585,648, filed February 10, 1922.

In forming a tube package, the end 6 of the tube is projected between a pair of blocks 7 mounted on a rotatable head, and the head is turned with the tube under suitable tension, resulting in the formation of a series of windings 8, one over the other, until the package is of the desired size.

To secure the outer end of the tube, the adhesive strip 4 is extended beyond the outer end of the tubing 2, as clearly shown in Figure 2, and is secured to the adjacent wrap of the package,

PAPER-TUBE PACKAGE.

difficult to locate the inner. end and as a result the outer label was "frequently torn and this resulted in an unwrapping of the entire package. Moreover, the use of the open center eliminates the sharp bends at the ends of the package, which sometimes cause the adhesive strip 4 to separate from the tube, thus resulting in an imperfect blasting tube.

I provide a blasting tube package wherein the inner end is readily accessible for unwinding and-with a simple and adequate sealing means for the outer end of the tube.

While I have illustrated the preferred embodiment of the invention, it will be understood that it is not limited thereto, but may be otherwise embodied within the scope of the following claims.

I claim:

1. A blasting tube package comprising a flattened tube having a pasted seam Wound upon itself to form a compact and self-sustaining package, the tubing being formed from paper and being of such strength and so tightly wound that the package is inherently self-sustaining, the outer end of the tubing being secured to an adjacent outer layer to prevent the tube from unwrapping, the package having an open center or core of substantially elliptical shape with well rounded ends and spaced apart side port-ions whereby sharp bends and reverse curves of the tubing at the interior of the package are eliminated and the tendency of the pasted seam to open is obviated.

2. A blasting tube package comprising a flattened tube having a pasted scam, the tubing being wound upon itselito form a compact and self-sustaining package, the tubing being of such size and stiliness and being so tightly wound that the package is inherently self-sustaining, the outer end of the tube being secured to an adjacent outer layer to prevent the package from unwrapping, the tubing being wound with the (ill pasted seam outwardly disposed and the package having an open center which is Well rounded at all portions and has substantially no reverse curves and no portions of tubing in contact with one another, Whereby opening of the pasted seam is eliminated, an inner Wrapping of the tube departlng from the regular Winding and pr0 ect1ng In testimony whereof I have hereunto set my hand.
